Question

what causes the sun to set every night? choose 1 answer: a earth rotating on its axis b the sun rotating on its axis c earth revolving around the sun d the sun revolving around earth

Explanation:

The sun appears to set daily due to Earth's rotation on its axis. As Earth spins, different parts move out of the sun's direct view, creating the sunset. The sun's rotation (B) doesn't cause Earth - based sunset. Earth's revolution around the sun (C) causes seasons, not daily sunsets. The sun doesn't revolve around Earth (D) as per heliocentric model. So the correct answer is the one related to Earth's axial rotation.

Answer:

A. Earth rotating on its axis
